Common knowledge about purchasing explosion-proof oil filter

It may be a little strange to say oil filter machine, and the working principle of oil filter machine may not be the focus of everyone's attention. For companies and enterprises, it is very important to choose oil filter and a brand. Today, the editor will tell you how to buy oil filter machine and precautions.

Generally speaking, there are many kinds of oil filter products on the market, and the appearance, function, use method and purchase cost of oil filter equipment are different. Therefore, if new and old users have the intention to buy oil filter machine, please learn more about oil filter machine so as to buy a more suitable product for themselves.

Precautions in the selection of oil filter machine:

First, choose and buy products with better quality. Before buying, you must see the product quality and some parameters clearly, and choose products with qualified quality.

Second, choose products with high cost performance.

1. The internal structure of the oil filter machine is different, and the oil filtering effect is also different. The oil filter machine of the first-level filtration level has a simple structure and is mainly composed of coarse filter elements, most of which can only be used for primary filtration.

2. Two-stage filter oil purifier. This oil filter machine has a set of coarse filters and a set of fine filters. Fine filters use hollow fiber filter elements, and the filtered oil is cleaner and more in line with the filtration standards. Multi-oil filters are medium-to-high-priced products.

3. Multi-stage filter oil purifier. It has multiple groups of filter elements for filtration, and the layers are denser. The filtration effect is better than the two-stage effect. Generally, the oil is seriously polluted, and the polluted oil meets the use standard.

Consideration factors

1. Filtration factors: temperature and viscosity, physical and chemical properties, unit time processing volume, filter cake moisture content, filtrate solid content and filter cake cleanliness are all factors to be considered when selecting an oil filter.

2. The filtering capacity of the oil filter per hour.

3. Filter pump type: The filtration rate pump of the oil filter is of two types: vertical and horizontal. The advantage of the vertical pump is that it is more suitable for filtering chemical plating liquid with large gaps, but the installation method is a little more complicated than the horizontal pump. Horizontal pumps include mechanical pumps and magnetic pumps. The former is more suitable for many solid particles, while the latter is less likely to leak without a shaft seal.

4. Filter materials of oil filter: The filter media of oil filter include wound filter element, non-woven bag, paper filter element, layered filter medium and microporous tubular filter element. There are also mixed types. Laminated filter material and microporous filter element have better filtering accuracy, but the former is troublesome to operate and the latter is easy to clog. Wrapped filter element has many uses, but it is difficult to clean.

Non-woven filter bags are easy to clean and use many times, but the source of the product has a great influence on the filtering accuracy. In short, each has its pros and cons. There are also activated carbon filter elements, which can be treated with mild activated carbon when working.

Common sense for purchase

1. Determine the type of oil to be processed (the oil products currently targeted by oil filter machines on the market are mainly transformer oil insulating oil, ordinary lubricating oil, turbine oil, and light fuel oil);

2. Are there any requirements for the amount of oil to be filtered and purified and the processing time?

3. How are you going to use the oil filter, such as online installation, mobile oil filtering, maintenance and standby, etc.

4. The main pollutants in the oil to be treated (whether it is simply filtered impurities or water impurities that need to be treated);

5. Whether the lubricating oil to be treated is corrosive, whether it needs to be neutralized by acid value, whether the oil is severely oxidized, whether the color of the oil needs to be treated, and other special properties.
